Chrysanthemum plant named ‘Fidcsunwhi’

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘Fidcsunwhi’, characterized by its upright to outwardly spreading and uniformly mounded plant habit; relatively compact growth habit; freely branching habit; dense and full plant form; uniform and freely flowering habit; medium-size decorative-type inflorescences with white-colored ray florets; early to mid-season flowering habit; and good garden performance.

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘FIDCSUNWHI’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially grown as a garden Chrysanthemum plant and hereinafter referred to by the name ‘Fidcsunwhi’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Fareham, Hampshire, United Kingdom. The objective of the breeding program is to create new early to mid-season flowering garden Chrysanthemum plants with numerous attractive inflorescences.

The new Chrysanthemum plant originated from a cross-pollination made in January, 2011 by the Inventor in Fareham, Hampshire, United Kingdom of a proprietary selection of Chrysanthemum×morifolium identified as code number 92122, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum×morifolium identified as code number 83277, not patented, as the male, or pollen, parent. The new Chrysanthemum plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Fareham, Hampshire, United Kingdom in September, 2011.

Asexual reproduction of the new Chrysanthemum plant by terminal vegetative cuttings was first conducted in Fareham, Hampshire, United Kingdom in December, 2011. Asexual reproduction by terminal vegetative cuttings has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Fidcsunwhi’. These characteristics in combination distinguish ‘Fidcsunwhi’ as a new and distinct Chrysanthemum plant:

-   -   1. Upright to outwardly spreading and uniformly mounded plant         habit.     -   2. Relatively compact growth habit.     -   3. Freely branching habit; dense and full plant form.     -   4. Uniform and freely flowering habit.     -   5. Medium-size decorative-type inflorescences with white-         colored ray florets.     -   6. Early to mid-season flowering habit, grown under natural         season conditions, plants flower in late August to early         September in the United Kingdom.     -   7. Good garden performance.

Plants of the new Chrysanthemum can be compared to plants of the female parent selection. Plants of the new Chrysanthemum differ from plants of the female parent selection in the following characteristics:

-   -   1. Grown under natural season conditions, plants of the new         Chrysanthemum flower earlier than plants of the female parent         selection.     -   2. Plants of the new Chrysanthemum have larger inflorescences         than plants of the female parent selection.

Plants of the new Chrysanthemum can be compared to plants of the male parent selection. Plants of the new Chrysanthemum differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Chrysanthemum are more compact than and not         as vigorous as plants of the male parent selection.     -   2. Plants of the new Chrysanthemum and the male parent selection         differ in ray floret color as plants of the male parent         selection have inflorescences with yellow-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Jasoda White’, disclosed in U.S. Plant Pat. No. 21,884. In side-by-side comparisons conducted in Fareham, Hampshire, United Kingdom, plants of the new Chrysanthemum differed from plants of ‘Jasoda White’ in the following characteristics:

-   -   1. Grown under natural season conditions, plants of the new         Chrysanthemum flowered about one month earlier than plants of         ‘Jasoda White’.     -   2. Plants of the new Chrysanthemum had larger inflorescences         than plants of ‘Jasoda White’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum plant.

The photograph is a side perspective view of a typical flowering plant of ‘Fidcsunwhi’ grown in a 19-cm container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the winter in 19-cm containers in a glass-covered greenhouse in Fareham, Hampshire, United Kingdom and under cultural practices typical of commercial garden Chrysanthemum production. During the production of the plants, day and night temperatures ranged from 17° C. to 21° C. and light levels averaged 6,000 lux. Plants were grown under long day/short night conditions for eight weeks (including propagation period) and then grown under short day/long night conditions to induce inflorescence initiation and development. Plants were 14 weeks old when the photograph and detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, except where general terms of ordinary dictionary significance are used.
